NEW YORK (CNN) -- A three-vehicle crash north of New York killed eight people, including four children, state police said on Sunday.

One of the vehicles in the three-vehicle wreck was heading the wrong direction, police said.

A fifth child is being treated for injuries suffered in the crash near Pleasantville, about 30 miles north of New York. Police initially reported no survivors.

The crash happened when a minivan carrying the five children and one adult was heading the wrong way on a northbound lane of the Taconic State Parkway, police said. It crashed head-on into an SUV carrying three adults.
